"The high-frequency section of the TWS600 is crisp & detailed. Just like the rest of the spectrum, the TWS600’s treble follows the main idea of an audiophile TWS. It is clear, extended, non-fatiguing. Mids are little forward, articulate, transparent, detailed. Upper mids may come a little too bright to some as there is a peak around 2k, so I’d be wary of that if you’re sensitive. Lower frequencies however, are not very present. Especially the sub-range is quite dry and rolled-off. Tonal balance takes a hit because of that, lacking in weight and essential harmonics. You don’t feel this while listening to Norah Jones but it can be easily noticed with music from say Tom Waits. Furthermore, instruments such as tubas, saxes and even piano take a hit from the bass response and they somewhat lack some body overall. Midbass is not very prominent but not as shy as the sub region, so that’s good. It has some body to it as well. Midrange and treble presentation gives a good boost to overall resolution. If we look at the sound stage layout, it welcomes us with a wide and relatively deep fashion, making it quite unique among other TWS earphones. "

If the flat response experience is what you're after, HiFiMan's TWS 600 earphones are one of the few pairs in the true wireless realm to deliver it. But compared to the $200 Klipsch T5 True Wireless and the $170 RHA TrueConnect, the design seems cheap—and the RHA TrueConnect, in particular, delivers excellent audio, along with a wide array of eartip options. The gym-focused $180 JBL UA True Wireless Flash and the not-at-all-waterproof $130 Samsung Galaxy Buds are also solid options, but are squarely in the boosted-bass realm.

While not the perfect earphone for every genre, this economical earphone does offer solid value for anyone bumping classical or pop tunes.

"The mid-range of the TWS600 has slight coloration to it and sounded boxy. The coloration is the most obvious in the upper mids where we can hear the male vocals becoming more squeak-ish at a higher pitch "

The HiFiMan TWS600 is one of the best true wireless headsets for people who want to wirelessly stream videos, but is underwhelming for most other uses. Audio clarity is disappointing as is microphone quality, but if you’re a sci-fi nerd and want something that looks like it belongs in an alternate universe, these just may be the earbuds for you.
